N750 Wireless Dual Band Gigabit ADSL Modem Router DGND4000

•You have problems connecting to your ISP or other Internet service, and the technical

support of either the ISP or NETGEAR recommends changing the MTU setting. These

web-based applications might require an MTU change:

-A secure website that does not open, or displays only part of a web page

-Yahoo email

-MSN portal

-America Online’s DSL service

•You use VPN and have severe performance problems.

•You used a program to optimize MTU for performance reasons, and now you have

connectivity or performance problems.

Note: An incorrect MTU setting can cause Internet communication

problems such as the inability to access certain websites, frames

within websites, secure login pages, or FTP or POP servers.

If you suspect an MTU problem, a common solution is to change the MTU to 1400. If you are

willing to experiment, you can gradually reduce the MTU from the maximum value of 1500

until the problem goes away. The following table describes common MTU sizes and

applications.

Table 11. Common MTU sizes

MTU Application

1500 The largest Ethernet packet size and the default value. This is the typical setting for

non-PPPoE, non-VPN connections, and is the default value for NETGEAR wireless

modem routers, adapters, and switches.

1492 Used in PPPoE environments.

1472 Maximum size to use for pinging. (Larger packets are fragmented.)

1468 Used in some DHCP environments.

1460 Usable by AOL if you do not have large email attachments, for example.

1436 Used in PPTP environments or with VPN.

1400 Maximum size for AOL DSL.

576 Typical value to connect to dial-up ISPs.

To change the MTU size:

1. Select ADVANCED > Setup > WAN Setup.

2. In the MTU Size field, enter a new size from 64 through 1500.

3. Click Apply to save the settings.
